    • Clear effluent from an aerobic sewage treatment tank is directed into one end of an elongated conduit adapted to be buried in the ground with the tank. The conduit has a length of many hundred feet and is preferably wrapped in the form of a substantially horizontal spiral coil. The opposite end of the conduit is vented to atmosphere, and a flow of air is directed from a supply pump through the conduit over the surface of the effluent to effect evaporation of the effluent into the air stream and discharge of the vapor with the air into the atmosphere. The air is directed into the conduit in a plurality of separate streams located at longitudinally spaced intervals and after moisture is removed from the air within a pressure-condensing container. The conduit is preferably formed of a corrugated flexible tubing of plastics material and may be constructed in a plurality of stacked coil sections which are connected in series.
    • 来自有氧污水处理罐的清除流出物被引导到适于与罐一起埋在地下的细长导管的一端。 导管具有几百英尺的长度,并且优选地以基本水平的螺旋线圈的形式包裹。 导管的相对端被排放到大气中,并且空气流从供应泵通过导管穿过流出物的表面,以将流出物蒸发到空气流中并将蒸气与空气一起排放到 气氛。 空气以多个分开的流引导到管道中,该多个分开的流以纵向间隔开的间隔和在压缩冷凝容器内从空气中除去湿气之后。 导管优选由塑料材料的波纹柔性管道形成,并且可以被构造成串联连接的多个堆叠的线圈部分。

    • THERE IS DISCLOSED AN IMPROVED SYSTEM FOR OBTAINING POTABLE WATER FROM HUMAN WASTE AND INVOLVING TWO EVAPORATORS HAVING A WASTE INLET IN COMMON AND A VAPOR OUTLET IN COMMON BUT SEGREGATED FUNCTIONALLY BY SUITABLY POSITIONED CONTROL VALVES. EACH EVAPORATOR IS OF CYLINDRICAL SHAPE, FORMED OF SEVERAL COMPARTMENTS OF DIFFERENT DIAMETERS, TWO OF WHICH ARE SECURED TOGETHER BY A CONICAL HOUSING. THE LOWERMOST COMPARTMENT IS HEMISPHERICAL IN SHAPE AND IS DETACHABLY SECURED TO THE ADJACENT COMPARTMENT. THERE ARE FOUR ISOTOPES IN THE LOWERMOST COMPARTMENT, ALSO A SINGLE ISOTOPE IN THE UPPERMOST COMPARTMENT. THE WASTE MATERIAL IS PUMPED INTO THE LOWERMOST COMPARTMENT WHERE IT IS HEATED AND THE VAPOR IS FORCED TO PASS THROUGH, IN SUCCESSION, A HEAVY LAYER OF "WICKING" MATERIAL, ALSO A PAIR OF HORIZONTALLY DISPOSED FILTERS, IN ADDITION TO A CIRCUMFERENTIAL FILTER. UPON REACHING THE UPPERMOST COMPARTMENT, THE VAPOR IS HEATED BY THE SINGLE ISOTOPE ENCLOSED IN A CASING FROM WHICH A NUMBER OF VANES RADIATE TO DISTRIBUTE THE HEAT. THE SPACE BETWEEN THE VANES IS FILLED WITH AN OXIDIZING CATALYST. THE VAPOR IS FED INTO A COILED PIPE LOCATED IN THE LOWERMOST COMPARTMENT WHERE IT GIVES UP ITS HEAT TO THE SURROUNDING WAST MATERIAL. THE VAPOR IS THEN CONDUCTED THROUGH A WATER COOLED CONDENSER, AND FINALLY TO A STORAGE TANK FOR CONSUMPTION. THE HEMISPHERICAL COMPARTMENT RECEIVES THE SEMI-SOLID PECIPITATE AND IS ADAPTED TO BE CLEANED BY THE ASTRONAUT BY REMOVING THE SAME AT THE DETACHABLE CONNECTION, AFTER A "SWITCH OVER" TO THE OTHER EVAPORATOR HAS BEEN EFFECTED BY THE VARIOUS VALVES.

    • A method for processing sewage eliminates chemical "treatment", or, the addition of chemicals that are as harmful or more so to the environment than raw sewage. The method of processing sewage disintegrates the generally solid components of sewage into a highly de-moisturized powder via alternative processes, the first being a freeze-drying process, wherein sewage (S) enters a settling tank (12) via inlet piping (14). The sewage then passes through a grinding pump (16), into a second holding tank (22), then into a freezer chamber (28), then into a vacuum chamber (42), and then into a storage station (50). A second process combining centrifugal separation and an evacuated "bake-out" step is also disclosed. Both porcesses drive out vaporizalble components from the sewage which would adversely impact the environment.
    • 处理污水的方法消除了化学“处理”,或添加比原污水对环境有害或更多的化学物质。 处理污水的方法通过可替代的方法将大部分固体废水分解成高度脱水的粉末,首先是冷冻干燥过程,其中污水(S)经由入口管道(14)进入沉淀池(12) 。 然后,污水通过研磨泵(16)进入第二容纳槽(22),然后进入冷冻室(28),然后进入真空室(42),然后进入储存站(50)。 还公开了将离心分离和抽真空的“烘烤”步骤相结合的第二种方法。 这两个工厂都会从污水中排出气体,这将对环境造成不利影响。
